We introduce a practical synchronous stream cipher with provable security named QUAD. The cipher relies on the iteration of a multivariate quadratic system of m equations in n <...
Abstract. There is great interest in applying nominal calculi--computational formalisms that include dynamic name generation--to the problems of programming, specifying, and verify...
Abstract. In this paper we describe the first implementation on smartcard of the code-based authentication protocol proposed by Stern at Crypto'93 and we give a securization o...

We propose two constructions of chosen-ciphertext secure identity-based encryption (IBE) schemes. Our schemes have a security proof in the standard model, yet they offer performan...
Adaptive security, while more realistic as an adversarial model, is typically much harder to achieve compared to static security in cryptographic protocol design. Universal composi...
